What are the dangers of a colostomy reversal procedure?

Quick Answer

The major dangers of a colostomy reversal procedure are bowel incontinence, a sore anus, anal leakage, excessive flatulence, and increased urgency and frequency of defecation, as noted by the National Health Service. Complications are less likely to occur when a loop colostomy is reversed than when an end colostomy is reversed.

The stoma for a colostomy can remain in place indefinitely, so doctors typically only perform colostomy reversals when conditions are close to ideal, according to the National Health Service. If the muscles of the anus were damaged during a prior surgery, chances for bowel incontinence after colostomy reversal greatly increase. It takes time for the anus to get readjusted to passing feces after a colostomy reversal, and soreness in the anus is common. In general, before undergoing colostomy reversal, a person must be fully recovered from the initial colostomy surgery and finished with any further treatments, such as chemotherapy.

It is very common for people who undergo colostomy reversal to suffer diarrhea or constipation after surgery, but this usually goes away in time, explains the National Health Service. For a period of time after surgery avoiding large fatty meals, citrus fruits, cruciferous vegetables and spicy food may minimize discomfort.
